沼田善子(1986)将日语提示助词「も」的用法分三类,即「も」1、「も」2、「も」3。三者的含义分别为:单纯他者肯定的、意外的、委婉的。本文通过分析「も」的虚拟化过程,借助Langacker(1991)识解的三种模式对「も」1、「も」2、「も」3的主观化进程进行验证。同时,从研究语气的成立、阶层以及凝固化等方面为「も」提供主观化论证依据。 Numata Takako (1986) classifies the usage of the Japanese clues “mo” into three categories: “mo” 1, “mo” 2, “mo” 3. The meanings of the three are: affirmative, accidental, euphemistic. This paper verifies the process of subjectiveization of “mo” 1, “mo” 2, and “mo” 3 by analyzing the virtual process of “mo” and using the three models that are interpreted by Langacker (1991). At the same time, it provides a subjective argument for “mo” from the aspects of the establishment of tone of study, class and solidification.
